Definitions

  • the invention relates to a device for checking a electric drive and / or one assigned to the drive mechanical device, in particular a fitting or is an actuator, the drive and / or the mechanical Setting up a unit that has connections is assigned, and being connected to the connections a diagnostic module can be connected.
  • a device for checking an electric drive or a mechanical device connected to it the a valve or an actuator may be necessary to the functional state of the drive and / or the actuator to be able to monitor. Through constant monitoring can timely disruptions or changes in operational behavior of the drive and / or the mechanical device recognized become.
  • the mechanical device is a valve or an actuator which e.g. Can be part of a power plant, is, one can make changes and / or damage the reliability not affect the valve or actuator yet, but a security related damage or Identify malfunctions early on.
  • a defective or malfunctioning drive and / or a defective or malfunctioning mechanical device can therefore be recognized early and then serviced, repaired or be replaced.
  • the electric drive is an actuator in a track system is assigned, in particular the Actuator of a railway switch can act.
  • EP 0 609 261 B1 describes a device for checking of an electric drive, in particular a drive of a Armature is known.
  • the drive is a structural unit assigned in the supply lines of the drive Voltage measuring lines go out that are connected to voltage taps end of the unit.
  • Supply lines assigned to current transformers via current measurement lines connected to power taps on the assembly are.
  • the current transformers are usually the supply lines without interrupting these supply lines, e.g. inductive, assigned.
  • a diagnostic module can be connected. This diagnostic module is included in the Known a diagnostic connector with a central measuring and Evaluation unit is connected. The diagnostic connector takes signals present at the connections and conducts them a line to the measuring and evaluation unit.
  • DE 39 36 988 C2 is designed as a plug Diagnostic module known that a signal processing arrangement contains. This arrangement must be done because the monitoring of a drive must be complete, constantly on a supply voltage source be connected. Because in the area of one to be monitored No suitable auxiliary power is available for the drive stands, the diagnostic module must either be complex Line supplied from the outside or with a relatively large bat terie. Therefore, it has not been economical so far a diagnostic module without permanent connection to a to construct a centrally positioned measuring and evaluation unit.
  • the invention has for its object a device for checking an electric drive or actuator and / or a mechanical device assigned to the drive specify, the device being a diagnostic module includes, on the one hand, not with a central evaluation unit must be connected and above in addition, only a relatively small supply power or one relatively small facility for energy supply needed.
  • a Power supply device available for the diagnostic module is connected to at least one of the connections on the assembly or can be activated via an external signal.
  • the diagnostic module over has two operating modes. As long as none to be processed Signals are present, the module is in an energy-saving Sleep mode. If there are one or more signals, the module goes into work mode. So you come advantageously in the diagnostic module with little energy, even if there is no central measuring and evaluation unit for one or more diagnostic modules is provided. For personal use of the diagnostic module, a small electrical one is sufficient Energy storage, e.g. a battery, or a small supply line with a small cross-section.
  • the diagnostic module is used as an energy supply device, for example an electrical energy store and / or Assigned voltage source, one of which to the diagnostic module Supply line leads.
  • the electrical energy storage can be rechargeable or non-rechargeable. He can also be an electrical capacitance. As a result of Such an energy supply is sufficient for the sleep mode Own requirement of the diagnostic module.
  • the energy supply device is, for example, via a signal present at at least one connection of the assembly the operating voltage and / or the operating current and / or the control voltage and / or by another signal switched on. Only when e.g. the operating voltage and / or the control voltage is applied to the drive, so it becomes the diagnostic module activated. As long as the drive is at rest, too the diagnostic module in sleep mode. Because the electric drive, e.g. is assigned to a mechanical device, only is turned on when the mechanical device moves should be, the diagnostic module advantageously remains very long in sleep mode.
  • one in the supply line of the diagnostic module arranged switch via a connected to the connection Signal of the operating voltage, the operating current and / or the control voltage of the drive and / or by another Signal can be switched. This will place the diagnostic module in the Work mode offset.
  • the diagnostic module contains, for example, an evaluation unit (Processor).
  • an evaluation unit Processor
  • a line connection too a central evaluation unit is then not required or you get along with a poorly performing line because a large part of the evaluations already in the diagnostic module is made.
  • the energy supply of such an evaluation unit is in the diagnostic module with a small device, e.g. Battery, or a small supply line, because the diagnostic module while the drive is in the stationary State is advantageously kept in sleep mode becomes.
  • the diagnostic module is, for example, calibratable and has in addition a calibration input and / or a calibration output on e.g. are connected to the evaluation unit. Any Signal inputs, e.g. at the calibration input, can Known values are fed, then at the calibration output Actual values are output.
  • the Transfer function (calibration curve) of the diagnostic module especially the evaluation unit, usually outside the Diagnostic module determined.
  • This transfer function is in Diagnostic module, e.g. stored in the evaluation unit, after e.g. entered via the calibration input has been. This allows you to assess the drive or the close the mechanical device to suitable values.
  • a data memory can be present in the diagnostic module e.g. is connected to the evaluation unit. There can be measured or calculated data are saved until the Diagnostic module for reading out and further processing of the data to an external evaluation unit is connected.
  • a setpoint memory can be stored with the evaluation unit in the diagnostic module connected that contains setpoints. If in the Evaluation unit is determined that measured or calculated Values exceed or fall below a setpoint, can be the drive or the associated mechanical device characteristic signal are given.
  • one or more reporting devices e.g. LEDs connected that indicate that data is available or saved.
  • the diagnostic module has the form of a plug, for example and the connections on the assembly are taps for receiving of the plug. This has the advantage that the Diagnostic module in a simple and quick way from a single unit can be moved to another, so that in short time several drives and / or assigned mechanical Facilities can be checked.
  • the diagnostic module can be a Breadboard to be, which is also easy from one assembly can be moved to another.
  • the diagnostic module can also be permanently installed be, it being necessary for each unit to be one Assign diagnostic module.
  • the diagnostic module can be a mobile one Be module that is easy to change and by suitable Devices with multiple drives or mechanical devices, e.g. in the common strand of energy supply can be.
  • the diagnostic module contains a reading device, the one with a coding connection of the assembly connectable coding input is connected. At the coding connection the unit has coding information to the drive to be checked or the mechanical Features. The advantage is achieved that when checking an electric drive or mechanical device, is automatically recognized immediately which of many drives or mechanical devices the diagnostic module is connected in a system.
  • the invention has the particular advantage that a Diagnostic module needs so little energy that in particular an evaluation unit and / or also a memory in the diagnostic module can be accommodated and energized, and that the diagnostic module is still so light and compact, that it was used in succession on different building units can be.
